The GMRT High Resolution Southern Sky Survey for pulsars and transients -- VI: Discovery of nulling, localisation and timing of PSR J1244-4708
Shubham Singh, Jayanta Roy, Shyam Sunder +2
Many pulsars in the known population exhibit nulling, which is characterised by a sudden cessation and subsequent restoration of radio emission. In this work, we present the locali…
The GMRT High Resolution Southern Sky Survey for pulsars and transients -- V: Localisation of two millisecond pulsars
Shyam Sunder, Jayanta Roy, Sanjay Kudale +3
The timing follow-up of newly discovered millisecond pulsars (MSPs) is hindered by the larger positional uncertainty (a few tens of arc-minutes) associated with the discovery. In t…
Decade Long Timing Study of the Black Widow Millisecond Pulsar J1544+4937
Sangita Kumari, Bhaswati Bhattacharyya, Devojyoti Kansabanik +1
Results from 11 years of radio timing for eclipsing black widow millisecond pulsar (MSP) binary, J1544+4937, is presented in this paper. We report a phase-connected timing model fo…
The GMRT High Resolution Southern Sky Survey for pulsars and transients IV: Discovery of 4 new pulsars with an FFA search
Shubham Singh, Jayanta Roy, Bhaswati Bhattacharyya +3
The fast Fourier transform (FFT) based periodicity search methods provide an efficient way to search for millisecond and binary pulsars but encounter significant sensitivity degrad…
The GMRT High Resolution Southern Sky Survey for pulsars and transients -- III: searching for long period pulsars
Shubham Singh, Jayanta Roy, Ujjwal Panda +5
Searching for periodic non-accelerated signals in presence of ideal white noise using the fully phase-coherent Fast Folding Algorithm (FFA) is theoretically established as a more s…
Wide-band timing of GMRT discovered millisecond pulsars
Shyam S. Sharma, Jayanta Roy, Bhaswati Bhattacharyya +6
Modeling of frequency-dependent effects, contributed by the turbulence in the free electron density of interstellar plasma, is required to enable the detection of the expected impr…
